Maturity: Lm ?  range ? - ? cm
Inhabits the intertidal zone of rivers and estuaries (Ref. 101380). Also in mangrove estuaries where it is often associated with the air roots of mangrove trees, coastal rocks and stones (Ref. 101381). Often seen attached to the stilt roots of the red mangrove Rhizophora spp., fringing lagoons and estuaries (Ref. 106421). Also found on low subtidal level attached to rocks, shells, or stones on muddy sand bottoms (Ref. 109255). Oyster assemblage confers protection and food for various invertebrates and fishes (Ref. 101381). Filter-feeder, feeds on phytoplankton (green algae, diatoms, dinoflagellates) and substrate particles (Ref. 106999). Members of the class Bivalvia are mostly gonochoric, some are protandric hermaphrodites. Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam (Ref. 833).
